Pregnancy is always a special case. Every action or side effect of a drug will change compared with the situation of a non pregnant patient. Not only is the metabolism of a pregnant woman different from the changes in hormones and other changes, but because every drug or its metabolite is passed to the baby and shows its effect there. The only thing is to be careful, careful and supervised when taking any medication during pregnancy. The interactions during pregnancy may vary and the dose may vary. It is mandatory to supervise the doctors strictly. Now let's know what happens when pregnant women take iron oxide drugs.

　　Carbonyl iron was not formally assigned to the pregnancy category by FDA. There is no controlled data in human pregnancy. The human case report did not reveal evidence of teratogenicity. Carbonyl iron can only be given during pregnancy, and the potential benefits outweigh the potential risks.

　　In general, iron is considered safe for use during pregnancy and is often prescribed as part of prenatal vitamin / mineral supplements. However, it is controversial whether routine iron supplements are needed in non anemic pregnant patients. Although FDA did not allocate iron to the category of pregnancy, the European Commission on patent drugs has assessed iron products as "A", defined as a drug product evaluated in pregnant women, and has no known harmful effects on pregnant and unborn and newborn babies. Anemia may be a risk factor for preterm birth and low birth weight. It should be diagnosed and treated as soon as possible before pregnancy or three months before pregnancy. Because supplementation of iron may reduce the dietary intake of zinc, it is also important to assess the state of zinc. Most antenatal vitamins also contain a full amount of zinc. If calcium is also a component of prenatal multivitamins, the absorption of iron and zinc may be reduced.

　　Ferric oxide breastfeeding

　　When a patient takes a medicine while breastfeeding, some of the drugs will be secreted into the breast milk and transmitted to the baby. The dosage of the drug is different to the mother and the baby. Many drugs play a side effect in the absence of a disease. What if the baby has no infection? If the drug is taboo in the newborn, baby or children? So, breastfeeding is a very shocking situation when the mother is taking medicine. Ask your doctor or pediatrician about the effects of drugs on the baby and how much excretion of the breast milk and whether it hurts the baby. The following information is the mechanism of iron oxide related to breastfeeding.

　　A study showed that the iron reserves of mothers supplemented by non anemic mothers (40 mg of iron within 3 months after delivery) were increased, without significant changes in milk iron concentration or lactoferrin, without harmful effects on infants. Another study evaluated oral iron supplementation for anaemia women who received 100 mg of iron per day for 2 days after delivery, and lasted for 30 days. Ten non anaemic women received iron supplementation during pregnancy. The concentrations of iron and lactoferrin in milk obtained from 2 and 30 days after childbirth did not differ between groups at any stage of lactation.

　　It has been reported that iron supplementation during lactation did not significantly affect the total iron concentration in human milk. Most clinicians often believe that the carbonyl iron administration during lactation is safe for infants.
